Objective: To review the characteristics and applications of Ora-Pro-Nóbis (OPN) (Pereskia aculeata Mill.), highlighting evidence of health promotion related to its consumption, as well as clarifying the current regulatory scenario. Literature review: OPN is an Non-Conventional Food Plant (PANC) that is easy to cultivate and has high nutritional value due to its high concentrations of proteins, fibers, vitamins (A, C, and B9), and minerals (calcium, iron, magnesium, manganese, and zinc). Preclinical and clinical evidence associates its consumption with potential health benefits, including anti-obesity, antioxidant, anti-inflammatory, analgesic, and intestinal modulatory activities. Additionally, investigations indicate an enhancement of longevity, neuroprotective effects, and improvements in metabolic parameters. The traditional use of OPN in culinary practices and folk medicine is extensive. However, as of this date (Dec/2025), the Brazilian Health Regulatory Agency (Anvisa) prohibits its use as an ingredient in dietary supplements, restricting its consumption solely to traditional food forms. Final considerations: The hardiness and broad applications make OPN production a viable alternative capable of adding value for small-scale farmers. However, further studies, especially clinical trials, must be conducted to investigate its safety and potential health benefits, thereby rationalizing the benefits associated with OPN consumption.

Revisión bibliográfica: La OPN es una Planta Alimenticia No Convencional (PANC) de fácil cultivo y elevado valor nutricional por sus concentraciones de proteínas, fibras, vitaminas (A, C y B9) y minerales (calcio, hierro, magnesio, manganeso y zinc). Evidencias preclínicas y clínicas asocian su consumo con potenciales beneficios para la salud, incluyendo actividades antiobesidad, antioxidantes, antiinflamatorias, analgésicas y moduladoras de la funcionalidad intestinal. Además, investigaciones señalan potencialización de la longevidad, efectos neuroprotectores y mejora de los parámetros metabólicos. El uso tradicional de la OPN en gastronomía y medicina popular es amplio. Sin embargo, hasta la fecha (Dic/2025), la Agencia Nacional de Vigilancia Sanitaria (Anvisa) veta su uso en suplementos alimenticios, restringiendo su consumo a las formas alimentarias tradicionales. Consideraciones finales: La rusticidad y las amplias aplicaciones de la OPN la convierten en una alternativa de valor para pequeños productores. No obstante, se requieren más estudios, sobre todo ensayos clínicos, que investiguen su seguridad y potenciales beneficios para la salud, racionalizando así los beneficios asociados al consumo de OPN.

This study evaluated the susceptibility of common bean (Phaseolus vulgaris L.) cultivars to Euschistus heros feeding across various phenological stages. Three cultivars (IPR Curió, IPR Sabiá, and IPR Urutau) were infested with 0.5 insects per plant for eight days starting at anthesis and 8, 16, 24, 32, and 40 days after flowering (DAF) using a randomized block design with five replicates. E. heros did not significantly impact grain yield or reproductive abscission, except for the IPR Curió cultivar during flowering, which demonstrated substantial qualitative damage. Feeding injury resulted in increased grain punctures and the grading of commercial classification to Type 2. The most critical susceptibility period occurred during the grain-filling stages (16–24 DAF). IPR Curió was the most sensitive cultivar, exhibiting Type 2 status at both 16 and 24 DAF. These findings demonstrate that although common beans exhibit quantitative tolerance to E. heros at the tested density, qualitative damage during grain development significantly compromises marketability and value. Integrated Pest Management (IPM) should prioritize protecting the crop during mid-to-late reproductive stages to ensure that grain quality standards are met.

This study focused on the characterization of Eucalyptus spp. raw materials to produce sawn wood, considering four genetic materials planted at different spacings. Seven-year-old forest stands were evaluated in the Nelder arrangement. Three hybrids of E. urophylla × E. grandis and one variety of E. saligna were selected, planted at three spacings (3.0 m × 3.0 m; 6.0 m × 3.0 m; and 8.5 m × 3.0 m). Trees were evaluated for size, shape, deformations, heartwood, bark, and quality. Tree and log characteristics were influenced by genetics, spacing, emphasizing selection for quality and sustainability in sawn wood production. E. urophylla × E. grandis had greater height and volume but more stress and cracks than E. saligna . Among the genetic materials tested, E. urophylla × E. grandis II showed superior characteristics for sawn wood production. The 3.0 m × 3.0 m spacing yielded higher wood volume per area, albeit with smaller tree dimensions. The 6.0 m × 3.0 m spacing resulted in trees with shapes like the 8.5 m × 3.0 m spacing, producing logs with comparable taper, bark thickness, heartwood percentage, and volume per area. Therefore, one of these larger spacings is recommended to produce Eucalyptus spp. wood for sawmills.

The maize leafhopper Dalbulus maidis (Hemiptera: Cicadellidae) is a key pest and vector of pathogens in Latin American maize, and its monitoring in the field currently relies mainly on yellow sticky traps, which present handling difficulties and low selectivity. This study evaluated LED-based light traps with different spectra and internal colors as alternatives for monitoring D. maidis while minimizing captures of non-target insects. Field trials were conducted in maize crops in Londrina, Paraná State, Brazil, in March 2023 and May 2025. The experimental design was a randomized complete block factorial (4 × 2 + 1): four light spectra × two internal trap colors + yellow sticky trap, in five temporal replicates. Traps were baited with LEDs emitting 372, 402 or 409 nm, or warm-white light (3000 K), and had either a white or black internal surface. Warm-white LEDs combined with a white internal surface captured 69-fold (2023) and 81-fold (2025) more D. maidis adults than yellow sticky traps; whereas 372 and 409 nm yielded captures similar to those of yellow traps. Spectra at 402 nm with a white background produced intermediate increases. Predatory insects were rarely captured (<1.5 individuals per trap on average) and did not differ among spectra or internal colors. Warm-white traps with white background also captured the highest numbers of other cicadellids, whereas moths were predominantly attracted to 402 and 409 nm, with relatively low capture under warm-white light. Overall, warm-white LED traps with a white internal background substantially improved D. maidis capture compared with yellow sticky traps, with minimal impact on predators and reduced moth capture. This configuration is a promising option for enhancing maize leafhopper monitoring in the field, although the high attraction of other leafhopper species may constrain its use in future automated detection systems.

The Brazilian Atlantic Forest, a critical biodiversity hotspot, plays a vital role in climate regulation and water conservation. To explore the relationship between tree diversity and soil bacterial communities, soil samples were collected along an edapho-climatic gradient. We hypothesized that tropical forest soils, among Earth’s most complex biological environments, exhibit predictable microbial community assembly patterns driven by deterministic processes. Specifically: (i) tree composition influences bacterial communities more strongly than abiotic factors when environmental heterogeneity is low, following niche-based assembly rules; (ii) specific tree taxa function as keystone species, shaping bacterial communities through microhabitat modification. Our findings indicate that tree diversity had a greater influence on shaping bacterial communities than soil attributes. Of the 72 tree species identified, Senegalia recurva, Araucaria angustifolia, Styrax acuminatus, Ilex paraguaiensis, Eugenia subterminalis, and Pisonia ambigua were key drivers of soil bacterial diversity. Additionally, late-successional tree species that require high light were closely linked to predicted microbial cycling of carbon, nitrogen, sulfur, and phosphorus. These results offer a hypothesis-generating framework for evaluating species selection in Atlantic Forest restoration projects, suggesting that these species represent candidates whose effects can enhance soil health and ecosystem functionality in reforestation programs.
